197.17 ES volt est interval
0.000...20.000 s
Description
Defines the time interval at which the energy storage
voltage (102.03 ES voltage
current is so small that the energy storage voltage cannot
otherwise be accurately estimated. Converter injects small
current pulses at the interval defined here to be able to
estimate the energy storage voltage. Pulses can either
charge or discharge the energy storage depending on the
current limits and energy storage voltage level.
Note: If you set this value to zero, you disable the current
pulses and make the energy storage voltage estimation
unreliable at a low current.
